Though we don't know exactly how a TZO comes to be, the prevailing theory is that a red supergiant star essentially swallows a tiny neutron star, which spirals into the center of the larger star and makes a home in its core. Since they can't identify a TZO by looking, scientists use their knowledge of the elements within it to detect them in its unique light spectrum.

Stars are basically element factories: their cores fuse hydrogen atoms into helium, helium into beryllium, and so on down the periodic table until they get to iron.

Once a star massive enough to fuse iron has done so, its core eventually caves in on itself until it's as dense as an atomic nucleus, then the entire thing explodes in a very giant supernova. That's how a Thorne-Żytkow object's neutron-star core is created: it's the very super-dense body that's left after a star has blown off its outer layers. The very elements that a garden-variety red supergiant create are predictable. But when that star has a neutron star in its core, those elements change very slightly.

Specifically, the researchers who discovered the first Thorne-Żytkow object noticed that its particular light spectrum pointed to excess amounts of rubidium, lithium, and molybdenum—pretty close to what physicist Kip Thorne and astronomer Anna Zytkow predicted when they theorized the existence of Thorne-Żytkow objects in 1975. It just goes to show that if you can imagine it, it probably exists somewhere out there in the universe. Learn more about strange space stuff in the video below.

As Spiderman’s Uncle Ben once famously said, “with great power comes great responsibility,” few responsibilities are more significant than that of being a father. And while parenting should be a shared responsibility, fatherhood, however, gives a different depiction of what raising children should look like.

Take these dads on our list for example. From innocently drawing eyebrows on your favorite daddy’s girl to provide them with more expression to using them as a plate, these funny dad jokes seem to have no end to them.#1 Two Kiwis
